Tool Holder Greasing Unit for Uniform Sliding Contact Lubrication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing bending systems face challenges in efficiently and consistently applying grease to the sliding contact parts of tool holders, leading to wear and affecting processing accuracy, with the current methods being time-consuming and prone to variation in application state.
Innovation Solution
A greasing unit that moves in the left-right direction, supported by a holder on the press brake's table, includes a greasing unit main body and an application member shaped to match the sliding contact parts, allowing for easy and uniform grease application by moving the unit between positions on the table.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If grease is applied manually with a brush to the sliding contact part, then the wear of the sliding contact part can be suppressed, but the work is extremely troublesome and time-consuming with variation in application state
Solution Approach 1:
The greasing unit is designed to automatically apply grease to the sliding contact part without manual intervention. The application member is automatically impregnated with grease and moved into contact with the sliding contact part, enabling the system to perform its own maintenance function and eliminating the need for manual greasing operations
Solution Approach 2:
The application member serves as an intermediary between the grease storage and the sliding contact part. It is impregnated with grease and then brought into contact with the sliding contact part, providing a controlled and consistent grease application mechanism that eliminates the variability of manual brushing
2Reliability
If manual greasing is performed, then some grease application is achieved, but variation occurs in the application state and wear prevention is insufficient
Solution Approach 1:
The automated greasing system performs the greasing operation autonomously without requiring manual intervention, thereby eliminating time loss and ensuring consistent application state through controlled movement and impregnation of the application member
Solution Approach 2:
The greasing unit can be operated continuously or periodically to maintain the sliding contact part, ensuring consistent grease application over time without the interruptions and variability inherent in manual greasing operations
